Cooler, drier weather is expected to clear the way for SpaceX to launch a Falcon 9 rocket and Japanese communications satellite from Cape Canaveral Air Force Station first thing on Friday, at 1:21 a.m.

There's less than a 10 percent chance of weather violating launch rules during the two-hour window at Launch Complex 40, according to the Air Force's 45th Weather Squadron.

But gusty winds around the launch pad will be watched as a potential threat.

Storms on Wednesday forced a one-day delay to the launch, which had been scheduled for 1:21 a.m. Thursday.

On top of the 230-foot Falcon 9 is the JCSAT-14 satellite owned by Tokyo-based SKY Perfect JSAT, Asia's largest satellite operator with 15 in orbit.

The mission aims to deliver the satellite on its way to an orbit more than 22,000 miles over the equator.

After the rocket's nine first-stage engines burn out, SpaceX will attempt to land the booster on a ship stationed in the Atlantic Ocean.

However, the company says a successful landing is unlikely because of the high speed at which the rocket will return to the ship. The attempt will be SpaceX's latest experiment aimed at developing a reusable Falcon 9 booster.

The company last month landed its first rocket stage at sea, and SpaceX CEO Elon Musk hopes to see it launch again this summer.
